1、安装前准备

Nagios安装前，首先安装相关主件，对于RHEL / CentOS系统: (依赖包的安装，其中httpd是为了是nagiox通过web界面显示出来)

[iyunv@server ~]#yum install -y wget httpd php gcc glibc glibc-common gd gd-devel make net-snmp

下载Nagios程序和Nagios插件

[iyunv@server ~]#wget http://prdownloads.sourceforge.n ... nagios-3.4.1.tar.gz

[iyunv@server ~]#wget http://sourceforge.net/projects/ ... ugins-1.4.15.tar.gz

2、添加Nagios用户和组　　

[iyunv@server ~]#useradd nagios

[iyunv@server ~]#groupadd nagcmd

[iyunv@server ~]#usermod -a -G nagcmd nagios

3、Nagios 安装

[iyunv@server ~]#tar zxvf nagios-3.4.1.tar.gz

[iyunv@server ~]#cd nagios

[iyunv@server nagios]#./configure --with-command-group=nagcmd

[iyunv@server nagios]#make all

[iyunv@server nagios]#make install

[iyunv@server nagios]#make install-init

[iyunv@server nagios]#make install-config

[iyunv@server nagios]#make install-commandmode

[iyunv@server nagios]#make install-webconf

复制nagios/contrib/eventhandlers目录下所有文件到/usr/local/nagios/libexec下：

[iyunv@server nagios]#cp -R contrib/eventhandlers/ /usr/local/nagios/libexec/

修改用户和主权限

[iyunv@server nagios]#chown -R nagios:nagios /usr/local/nagios/libexec/eventhandlers

校验Nagios配置文件，验证配置是否有误

[iyunv@server nagios]#/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

重启nagios、httpd

[iyunv@server nagios]#/etc/init.d/nagios start

[iyunv@server nagios]#/etc/init.d/httpd start

修改配置文件

[iyunv@server nagios]#vim /usr/local/nagios/etc/objects/contacts.cfg

修改nagiosadmin（这里修改为你自己创建的帐号） 注：nagiosadmin是配置文件默认，可以不用修改。

创建一个默认用户登录Web界面访问: 创建HTTP认证用户登录Nagios，用户名nagiosadmin，密码123456

[iyunv@server nagios]#htpasswd –c /usr/local/nagios/etc/htpasswd.users nagiosadmin

4、Nagios插件安装

[iyunv@server ~]#tar zxvf nagios-plugins-1.4.15.tar.gz

[iyunv@server ~]#cd /nagios-plugins-1.4.15

[iyunv@server nagios-plugins-1.4.16]#./configure --with-nagios-user=nagios --with-nagios-group=nagios

[iyunv@server nagios-plugins-1.4.16]#make

[iyunv@server nagios-plugins-1.4.16]#make install

5、Nagios服务设置

以下命令将寄存器Nagios守护进程运行在系统启动。

[iyunv@server ~]#chkconfig --add nagios

[iyunv@server ~]#chkconfig --add httpd

[iyunv@server ~]#chkconfig nagios on

[iyunv@server ~]#chkconfig httpd on

6、登录到WEB界面

输入用户名密码:nagiosadmin  123456

http://localhost/nagios

7、FQA

如果WEB无法访问，检查一下IPtables是否关闭。

[iyunv@server ~]# service iptables status
